[Wien] Input of structure of random alloy in Wien2k

[Yundi Quan]

If I were you, I would do the following.
First, find out alpha, beta, gamma according to your lattice vectors by
using cos(alpha)=(b vector dot product c vector) divided by {( modulus of b
vector) times (modulus of c vector)}.
In wien2k, choose P1 symmetry. Input a,b,c and alpha,beta, gamma and atomic
positions. If your atomic positions are given in Cartesian coordinate, you
might also need to rewrite them in terms of lattice vectors.
Then, run init_lapw.
In x nn and symmetry, WIEN2k will help you find equivalent positions and
symmetry which can save your computation time.
